Absorption illumination of a 2D rotator semi-infinite thermoelastic medium using a modified Green and Lindsay model

Abstract

In this work, the effect of rotation field can be studied during the modified Green and Lindsay model (MGL). The two dimensional (2D)elastic medium is exposed to thermal influences caused by surface absorption of (pulsed) laser radiation. In this case, The non- Gaussian temporal profile is used for the impact of the pulsed laser and the spatial one is a Gaussian. The two integral transformation Hankel and Laplace method are used with some surface conditions subjected to free traction to obtain the main fields. The complete general solution of the physical quantities are obtained using the inverse of Laplace transform numerically. With neglected the carrier density, the Silicon (Si) material is used as an elastic example medium to verify from the obtained results under the impact of rotation during the new (MGL) model.
